Anyone have any ideas why the heating circuit pressure on my Glow.worm Flexicom 24cx combi is rising, apparently via the domestic water cold supply? With the domestic H.W cold inlet isolated the heating circuit pressure remains constant.
Presumably there is an internal leak between components somewhere but don't know where this could be.
There was a small leak recently from the bottom of the casing but this was intermittent and stopped after three or four days. Otherwise the system is running normally.
Before removing the casing I wondered if someone could point me in the right direction.
